If you have sweet potatoes sitting in your pantry for a while, it is essential to check them before cooking. Eating bad sweet potatoes can cause food poisoning and other health problems. But how do you tell if sweet potato is bad? In this article, we’ll show you how to identify the signs of bad sweet potatoes and store them properly to extend their shelf life.
One of the first things to look for when checking if a sweet potato is rotten is its appearance. A fresh sweet potato has smooth, firm skin with no cracks or bruises.
How to Tell If Sweet Potato Is Bad?
If your sweet potato is oozing, smelly, discolored, and soft to the touch, it is not good for eating. Also, if you notice any soft spots, mold, or discoloration, it’s a sign that the sweet potato is going bad. Additionally, if the sweet potato has sprouted or has green spots, it’s time to toss it out.
If you’re wondering how to tell if sweet potato is bad, there are a few key indicators to look out for, the smell test and the texture check.
The first way to tell if your sweet potato is bad is to sniff it. If it has gone bad, it will emit a foul odor that is hard to miss.
The smell will be musty, moldy, or rotten. If you detect any of these smells, it’s best to discard the sweet potato immediately.
The second way to tell if your sweet potato is bad is to feel the texture. A fresh sweet potato should be firm and smooth to the touch.
It will feel soft, mushy, or slimy if it has deteriorated. Additionally, if you notice any discoloration or mold growth on the skin, it’s a sign that the sweet potato has spoiled.
Sweet potatoes turn black on slicing
When you slice a sweet potato, it is normal for the flesh to turn slightly darker due to oxidation. However, if the sweet potato turns completely black, it is a sign that it has gone bad and should not be consumed.
The black color is caused by the breakdown of the sweet potato’s sugars, which can occur when stored improperly or for too long. This can happen even if the sweet potato looks fine on the outside.
If you notice that your sweet potato is sitting sliced for a long time and it has turned black, it is best to discard it.
Store sweet potatoes in a cool, dry place with good ventilation to keep them fresh.
Avoid storing them in the refrigerator, as this can cause them to develop a rigid core and an unpleasant taste.
What does a spoiled sweet potato look like inside?
A spoiled sweet potato will be whitish from the inside. The fresh sweet potato has orange or brown flesh inside. A rotten one has mold growth inside that changes the color of the inner flesh.
If you see any discoloration and mold, discard the sweet potato.
How to Store Sweet Potatoes?
When storing sweet potatoes, you should keep a few things in mind to ensure they stay fresh for as long as possible. Here are some tips on how to store sweet potatoes:
- Choose the right spot: Sweet potatoes should be stored in a cool, dark, and well-ventilated place. A pantry or a cupboard is a good option. Avoid storing them in the refrigerator as the cold temperature can change the texture and taste of the sweet potatoes.
- Don’t wash them: Remove any dirt or debris on the skin before storing sweet potatoes. However, please do not wash them; excess moisture can cause them to rot quickly. Instead, dry them with a clean cloth or paper towel.
- Keep them dry: Moisture is the enemy of sweet potatoes. Store them dry and avoid wrapping them in plastic or airtight containers. Instead, use a breathable bag or a perforated plastic bag.
- Separate them: Sweet potatoes release ethylene gas as they ripen, which can cause other produce nearby to spoil faster. To prevent this, store sweet potatoes separately from other fruits and vegetables.
By following these simple steps, you can extend the shelf life of your sweet potatoes and enjoy their delicious flavor and nutrition for longer.
